GEORGE F. JACKSON. OF BYLLESBY, VIRGINIA.

GAS AND AIR MIXER.

Application filed June 17. 1938, Serial No. 240,557.

To all le/mm it may (-mu'e'rn:

lie it known that I, (luonoi: F. Jamison. a

eitizeu of -the l nited States, residing at llylleahy, in the eounty' of Carroll and Nate o Virginia. have invented eertain new and.

useful Improvements in "HS and Air Mixersfof whieh the following is a S|)(('lfiCt tioii. a

This inventimrrelutes to internal eomhustion engines, and'more espeeially to chargei'orniing devieea: tind the ohje t of the. same is to produre an improved ga and air mixer wherehy the eharge after it passes he earhureter run he diluted with either eold air or warm air or hoth. as the operator prefers.

A further ohjeet of the invention is to use the (llVlt'P for eooling the e vlinders when roasting or running on little power.

()ther ohjeets are aeeolnplished by this invention whose details will he set forth in the following upeeifieation. refereni'e heing made to the drawings. wherein Fi ure l is a side elevation of an automobile motor equipped with this invention.

Fig. 2 is a detail of one of the valves.

Fig. ll is a plan view of the parts just in rear of the fan.

Fig. 4 is an enlarged sectional the line 44 of Fig. 1.

Forward of the dash D of an automobile is loeated the engine whereof we are eoneerned onlv with the earhureter the inlet manifold M leading to the cylinders, the exhaust manifold E leading therefrom. the water pipe \l' leading to the radiator It. and the tan F. All these parts niay he of the usual or of any preferred eonstruetion. as my invention is applieahle to engines of a. variety of makes with little niodiiiration if an i will any at starting that it is posaihle that the earhureter he fed with-warm air through a pipe 1 leading from a box 2 elanding adjaeent the exhaust manifold E no is now quite eonimon. hat the air so enteriug the earlmreter is mixed with the vapor and forms part of the eharge Wlllt'll flows through the manifold M to the cylinders in a manner well understood.

(oming now to the details of the present invention. in the fork of the manifold I insert a plug 3 having a jet orifice at its inner end, and to the outer end of the plug is eonneeted a pipe 4 leading to a T-coupling 5 detail on Specification of Letters Patent.

whose shank or stem is connected with said pipe and whose head is open at its extremes. Just in rear of the fan F I place a colleetor, here shown in the shape of an elbow 6, from whieh a pipe 7 leads to the rear, through a valve 9. and theme along another pi e 9 into the head of the T-eoupling 5. Ipon the rear portion of the exhaust manifold E a ho. i2 is held hr :1 elip 19 or otherwise so that the air entering said box is heated, and a pipe IT leads from this box through a valve 13. and theme through another pipe ll! into the other end of the head of the T- roupling llneh valve has a stem 16 imvided with a erank l? as heat seenin l ig. 2. and pivoted to the (ranks of the two valves are rods 2!) and 21 leading rearward and upward through the dash I) and havin knolu: or heads 22 on their rear ends, stun ing within reach of the operator.

Ordinarily hoth valves 8 and 18 Will Stand rinsed. The suction of the earhureter now draws air through the pipe 1, which air has already heeu warmed in the box 2, and the eharge so formed is delivered through the manifold M to the rvlinders as usual. When it is desired to dilute the eharge after it leaves the earhnreter. it can be done by admitting air whieh is either hot or cold. The air drawn in through the radiator by the fan F is hlown into the rolleetor 6 and along 7. and ob iously when the valve 8 this air passes through the pipe i and eoupling 5, down the pipe 4 and through the plug or nozzle 3 into the manifold at the point. shown: and thereby the mixture within said manifold is diluted with eold air. (in the other hand. 'if the valve 8 is rinsed and the valve 18 is opened, the sue-tion within the manifold draws air from the box 12 whieh has already been heated b its proximity to the exhaust manifold and therefore the charge in the manifold is in this ease diluted with air which is heated. Henee the operator lute the eharge with either cold or warm air. and in some eases both. I find that when the maehine is roasting or running on very low power. it is quite possible to admit cold air which, while dilutio the mixture serves to eool the cylinders. en an engine on the other hand is doing much labor, as for instanr-e in ascending steep hills, I find it ad visable to admit warm air to the manifold if,

the pipe is opened.
